Titanium back up pro issue?

All of sudden I can't seem to get the Titanium back up pro> backup/restore or schedules tabs to open up. It just sits on the overview tab. It seems to be working otherwise, is this normal? I used to have all functions working before buying this app. I had the issue with CM7 rom and now using MIUI rom same thing no go. Any help is appreciated.

UPDATED:Got it to work using the eye sensor on my INC. For some reason the touch screen input method doesn't work for moving to the other tabs but the sensor does...???? Oh well it's working again in any case. Hope this might help someone else with this possible issue.
